Vorwort
Ich erinnere mich noch daran, dass um 2015 die Webentwicklung noch von jQuery dominiert wurde. Obwohl Vue und React populär wurden und Angular später auch begann, den Markt zu erobern, nimmt jQuery immer noch einen großen Marktanteil ein. Die meisten HTML-Seiten wurden damals mit jQuery geschrieben, und es gab eine ganze Reihe von Plug-Ins, die für jQuery entwickelt wurden. Beispielsweise ist es sehr praktisch, jquery.js in Kombination mit jquery.easing.js zu verwenden, um Animationseffekte zu erzielen. Der Grund für die Verwendung der Erweiterungsbibliothek jquery.easing.js liegt darin, dass die animierte Animationsmethode von jQuery weniger voreingestellte Geschwindigkeitsparameter aufweist und jquery.easing.js Ihnen dabei helfen kann, spezielle Animationseffekte zu erzielen.
$(selector).animate({params},speed,callback)
// 参数说明：
// params：必需的，参数定义形成动画的 CSS 属性；
// speed：可选的，参数规定效果的时长，如："swing"，"slow"，"fast"，"linear"，"normal" 或 毫秒数值；
// callback：可选的，参数是动画完成后所执行的函数名称；Spickzettel zur Easing-Funktion : https://easings.net/zh-cn
1. Das Vue-Projekt führt jQuery ein
(1) Abhängigkeiten importieren
npm i jquery(2) Verwendung
import $ from 'jquery'
import jQuery from 'jquery'
console.log($('body'))
console.log(jQuery ('body'))2. Fügen Sie die Erweiterung jQuery.easing hinzu
(1) Laden Sie nach Belieben eine jquery.easing.js- Datei herunter
(2) Formatieren Sie den Code dieser Datei, um die Codeextraktion zu erleichtern
(3) Wenn es sich um ein Vue2-Projekt handelt, fügen Sie einfach den folgenden Code zur gemounteten Lebenszyklusfunktion der Vue-Seite hinzu. Wenn es sich um ein Vue3-Projekt handelt, fügen Sie den folgenden Code zur onMounted- Lebenszyklusfunktion der Vue-Seite hinzu
